The Effect of Addition of Aluminum Oxide to the Base of Denture Resin Acrylic Heat Polymerization on Violence and Surface Roughness

Introduction

Heat polymerization acrylic resin (RAPP) has been the primary choice for making artificial dentures due to its numerous advantages, including good aesthetics, ease of repair, and relatively affordable costs. However, RAPP has several weaknesses, particularly in mechanical properties such as violence, and physical properties such as surface roughness. To overcome these limitations, recent research has focused on the addition of aluminum oxide (Al₂O₃) or alumina as an amplifier. The main purpose of this study was to examine the impact of the addition of aluminum oxide on the violence and roughness of the surface of RAPP.

The Importance of Mechanical and Physical Properties in Denture Resin

Mechanical properties, such as violence, are crucial in denture resin as they determine the durability and endurance of the denture. A denture with high violence can withstand the pressure and friction experienced during daily use, ensuring the comfort and well-being of the patient. On the other hand, surface roughness is an important factor in making dentures as it affects the comfort and irritation of the oral tissue. A smoother surface will make the denture more comfortable to use and reduce the possibility of irritation in the oral tissue.

Research Methods

The research design used in this study was an experimental laboratory design. In this study, RAPP samples were made without and with the addition of aluminum oxide with a concentration variation of 7.5%, 10%, and 15%. The sample size used for the hardness test was 60 mm x 10 mm x 3 mm, while the surface roughness test was 80 mm x 10 mm x 3 mm. In total, there were 48 samples, consisting of 24 samples for each violent test and surface roughness test. The test was carried out using an independent T test to identify the effect of aluminum oxide on the nature of being tested.

Research Results

The results showed a significant influence of the addition of aluminum oxide on the violence and roughness of the surface of RAPP. The significance of the P value obtained was 0.0001, which means P < 0.05, shows that the addition of aluminum oxide has a positive impact. In addition, research found that violence and surface roughness of RAPP increased along with an increase in aluminum oxide concentration. The optimal concentration recommended to be applied was 7.5%, which gives the best results in increasing violence and reducing surface roughness.

Analysis and Discussion

The addition of aluminum oxide to RAPP can increase material hardness, which is important for endurance and durability of dentures. Aluminum oxide is a material that is known to have high violence and resistance, so that when added to the RAPP, these properties can be obtained better. By increasing violence, RAPP becomes better able to survive the pressure and friction experienced during their daily use.

In addition, surface roughness is also an important factor in making dentures. A smoother surface will make the dentures more comfortable to use and reduce the possibility of irritation in the oral tissue. This study shows that the addition of aluminum oxide also contributes to reducing surface roughness, which has a positive impact on user comfort.

The Role of Aluminum Oxide in Improving Denture Resin Properties

Aluminum oxide has been widely used as an amplifier in various materials, including denture resin. The addition of aluminum oxide to RAPP can increase material hardness, which is important for endurance and durability of dentures. By increasing violence, RAPP becomes better able to survive the pressure and friction experienced during their daily use. In addition, surface roughness is also an important factor in making dentures. A smoother surface will make the dentures more comfortable to use and reduce the possibility of irritation in the oral tissue.

Conclusion

This study provides valuable insights on the role of aluminum oxide in improving the mechanical and physical properties of heat polymerization acrylic resins. With the right addition, aluminum oxide not only increases violence, but also reduces surface roughness, so as to produce better dentures. In the future, further development in the use of alumina can be an important step in material innovation for dentistry, with the hope of improving the quality of life of patients who need dentures.
